Can I use the DS7 in a single phase application?

We cannot use in single phase applications. The DS7 is design for the European single phase system which is 208-240V. In North American where the method of accessing 240 single phase is via two hot sources we will create an issue with the DS7 since there is no “neutral” as they have in Europe. what happens is the the DS7 is only recognizing the 120 Vac that are going through the SCR’s and will produce an LED error light. The device will not operate on 120 Volt single phases system as it is rated 208-240 single phase.
